(cites-.6) I v v This invention relates to amultiple pan. set of The present invention has in view .the, reinthe type commonly referred to as a muffin pan forcement of the rim of the mounting frame; in setwherein a series of pans are arranged in such a manner that the rim -is,not only =subspaced relation and secured togetherby a relastantially stiffened but the face of the mounting tively broad, flat mounting frame of sheet metal frame'adjoining said rim is protected against ,deor the like, having depending flanges at its formation as well as abrasive wearperiphery to form a rim substantially coexten- Reference being had moreparticularly to the sive in height withthe depth of the pans surdrawing, H) represents a frame consisting .of a rounded thereby. v relatively broad, flat vpieceof sheet metal of'the Among its other objects, the present invention type, commonly employed in the manufacture of 10 contemplates a multiple pan set of this type inmufiin pan. frames, having' a. plurality of opencluding the formation of a supporting rim at the ings of a transverse dimension slightlyles's than periphery of the set and the reinforcement and. the corresponding'dimension of each pan element protection of the face of the mounting :frame ll mountedtherein. The number of openings It is also an object of the present invention to desired to have in the frame. .Likewise,the shape provide tying members between the rims at orrdesign of the openings is controlled by the opposed edges of the set which will span the shape of thepan elements used. .As will 'be a space between transversely aligned rows .of;.the observed in'Figa m 7 e i ed b ween ing frame in said region. openings in the frame through which connection With the above and other objects in view, as between therpans- I [and the frame in is estabwillbe apparent, this invention consists in phe llShd. It .Will' be manifest hOWGVBI, that :the construction, combination and arrangement of set shown in the drawing maybe modified by parts, all as hereinafter more fully. described, employing a frame lflt having t penelements' 25 claimed and illustrated in the accompanying ll Dressed p from e y of the frame drawing, wherein: without departing from, the essence of this inven- Fig. 1 is a fragmentary plan view of a multiple tion.

The Strap ay be made of a the periphery of the mounting frame. In other S le Strap bent to'surround the pe p of e instances, the flange or rim has been surrounded flange l3, t maybe made p in S tions abut- 45 by means composed of an iron strap which'bears ting Overlapping at their ends s S own n Figs. against the upright face of the flange to be 2 and In Producing this type j nt, the secured thereto in any suitable manner. This t p sections-are p ly ut away to create type of rim construction provides no reinforcetongue ateaeh end of t v pp s ement for the body or upper face of the mounting ns of the strap l1, and the tongue .l8 of the 50 frame adjoining the rim and usually does not overlying section of the strap I1 is confined in a provide for protecting the corners of the face mutually depressed portion of the j underlying of the mounting frame against abrasive Wear section of strap I1, as more clearly shown in Fig. incident to handling of the set in commercial 4 Thus the sides or rim of the pan set may be 5 practice. a .moved in sliding contact with the corresponding enclosed by the flange I3 to complete the union of the various elements.

The upper edge of the strap I! is provided with a laterally projecting lip 2| which overhangs a corresponding portion of the brace and the top marginal portion of the frame Ill adjoining the flange I3. To obtain a continuous flush face in this region, the body of the frame I may be countersunk as at 22 to compensate for the thickness of the lip 2| of the clamping strap II. Obviously, the triple-ply construction thus provided in the region of the top marginal portion of the frame I0 adjacent tothe flange I3 creates a relatively stiff shoulder adapted to resist shearing strain at the juncture of the flange I3 and the body of the mounting frame III, as well as to eliminate abrasive wear on the exposed face of the frame I0.

The lower edge of the strap I1 is provided with a lip 23 which underlies the bottom edge 24 of the edge portion I3 of the frame Ill, as wellas the bottom edge 25 of the brace enclosed by said flange or edge portion I3. The width of the strap I! is preferably such as to locate its lip 23 in a plane substantially flush with the bot tom of the pans l0. Consequently, slight variations in the depth or width of the flange I3 arising in the process of manufacture may be accommodated without altering the desired coplanar relationship of the pan bottoms to the bottom limits of the strap I'I.

Interposed between transversely aligned rows of pans II is a tying member or bar 25. This tying member 26 is preferably arranged in edgewise abutment with the underside of the frame I and is secured thereto by clips 2! riveted as at 28 to the frame II). Extensions 30 at each end of the tying member 26 are bent angularly to rest flush against the inner face of the braceenclosed by the flange I3 of the frame In at transversely remote limits of the set and secured rigidly thereto by rivets 29 passing through the extensions 30, as well as the flange I3 and the brace and strap which enclose the flange l3. In this manner the body of the frame Ill between the sides and ends thereof is braced both by'the tying member 26 and the reinforced rim at the edges of the pan mounting frame Ill, to provide a structure of maximum rigidity.

What is claimed is:

1. In a multiple pan set, a plurality of pans, a substantially flat sheet metal frame for mounting and uniting said pans in spaced relation-' ship, the periphery of said frame being bent downwardly to create a flange, a brace having a vertically disposed portion in contact with the inner surface of said flange and a laterally disposed portion in abutment with the underside of said frame, a clamping strap surroundingthe outer surface of said flange and having portions in overlying relation to a portion of the frame 5 adjacent to said flange and in underlying relation to the lower limits of said flange and the brace enclosed thereby, means for securing said brace, flange and strap in rigid assembly, and

tying means extending between transversely aligned rows of said pans and in abutment with the underside of said frame, and secured thereto. 2. In a multiple pan set, a plurality of pans, a substantially flat sheet metal frame for mounting and uniting said pans in spaced relationship, the periphery of said frame being bent downwardly to create a flange, a brace having a vertioally disposed portion in contact with the inner surface of said flange and a laterally disposed portion in abutment with the underside of said frame, a clamping strap surrounding the outer surface of said flange, a lip at the upper edge of said clamping strap enclosing a portion of the upper face of said frame adjacent to said flange, a lip at the lower edge of said clamping strap underlying said flange and said brace and substantially coplanar with the bottoms of said pans, a tying member extending transversely of and in abutment with the underside of said frame, and means for securing 'saidtying member to said flange including means for securing said flange brace and clamping strap in rigid assembly.

3. In a multiple pan set, a plurality of pans, a substantially flat sheet metal frame for mounting and uniting said pans in spaced relationship, the periphery of said frame being bent downwardly to create a flange, a brace in abutment with the inner face of said flange and having a laterally disposed portion in abutment with the underside of said frame, a clamping-strap surrounding the outer surface of said flange, a second clamping strap complementary to the clamping strap aforesaid to form a continuous clamping strap surrounding the periphery of thepan set, a tongue formed at the end of one of said straps, a mutually depressed portion in the meeting end of the other of said straps for receiving the tongue aforesaid, and means for securing said clamping strap, flange and brace in rigid assembly including a rivet penetrating said tongue and mutually depressed portion in said straps.
